To all whom it may concern: of the clutch by means of such fork and pins Be it known that I, EDWARD T. HOFFMAN, 12, engaging in a circumferential groove 13 of Summunduwot, in the county of W'yanin the section 12, said section being actuated dotte and State of Kansas, have invented cer by said lever to throw it in or out of connectain new and useful Improvements in Dirttion with the section 11, so that the shaft 9 55 Loading Machines, of which the following is will transmit motion to the sprocket-wheel a full, clear, and exact description, reference 10, or allow the same to remain idle, as may being had to the accompanying drawings, be desired. 7

said roller being journaled to bars 30, said bars being secured adjustably to the frame 18 by means of slots 31 and set-screws 32.

33 represents extensions on the frame 18, which prevent the dirt from falling off on either side.

34 represents rods by which the frame .18 is braced with the main frame 1.

35 represents a beam secured to the frame 1 and extending out at an angle with the body of the frame. To the beam 35, I secure a curved casting 36, having a shoulder 37, (see Fig. III,) which, with the aid of bolts, forms a solid connection between the casting and the beam.

38 represents a scraper-blade, secured to the lower end of the casting 36by means of bolts 39.

It will be noticed that, owing to the shape and arrangement of the casting 36 and scraper 38, as the machine is traveling forward the dirt will be gathered in from a considerable distance and forced in toward the bottom of the conveyer, the blades of which gather it up and convey it to the top of the frame 18 and dump it into an accompanying vehicle.

40 represents a hood or shield, which prevents the dirt from falling under the lower end of the conveyer as it is thrown up by the scraper. The front axle 41 has an arched portion 42. The tongue 43 is attached to the axle by means of side bars 44 45 and a top bar 46.

47 represents the king-bolt, which extends from the portion 42 of the axle to the main portion. forward end of the frame.

48 represents a lever pivoted to the front axle, said lever being connected to the forward end of the frame 1 by means of a chain 49.

50 represents a pawl on the lever, said pawl being operated by the usual trigger 51.

g 52 represents a rack in which the pawl works. The object of the lever 48 is to raise or lower the front end of the frame 1, and thus raise or depress the scraper-blade, according to the condition of theground, &c.

I secure to the bar 53 a caster-wheel 54, which serves as an additional support and avoids all danger of the machine tipping over or becoming strained by the weight of the frame 18. e

In a dirt-loading machine, the combination, with a suitable supporting-frame and 5 wheels on which it is mounted, of an endless conveyer, means for operating said conveyer, and a scraper secured to the frame and adapted to throw the dirt onto the conveyer, said scraper being set at an angle and extending beyond the outerline of the drive-wheels, substantially as described, and for the purposes set forth.

2. In a dirt-loading machine, the combination of a suitable frame mounted on wheels, of an endless conveyer carrying blades adapted to enter the dirt, suitable driving mechanism connecting the conveyer with said wheels, and a scraper adapted to enter the earth and throw the dirt onto the conveyer, said scraper being situated to one side of the machine, set at an angle thereto and extending beyond the outer line of the drive-wheels, substantially as 'described, and for the purpose set forth;

3. The combination, in a dirt-loading machine, of an endless conveyer with blades adapted to enter the earth, and a device for throwing the dirt against the blades, said device consisting of the beam 35, curved casting 36, having a shoulder 37, and a blade 38, secured to the casting, substantially as described, and for the purpose set forth.

4. The combination, in a dirt-loading machine, of a suitable frame mounted on wheels, a scraper attached to the frame, said scraper extending at an angle beyond the outer line of the drive-wheels, and an endless conveyer consisting of a series of conveyer chains, bracket-links in the chains, and blades secured to the bracket-links, substantially as described, and for the purpose set forth.

5. In a dirt-loading machine, the combination of a scraper secured to a suitable frame, the drive-wheels, said scraper extending at an angle beyond the outer line of the drivewheels, an endless conveyer, and a hood located at the lower end of the conveyer, said hood serving to confine the dirt thrown up by the scraper, substantially as described, and forthe purpose set forth.
